CENTER-PLATE.

i Specification of Letters Patent.

Patented Jan. 4, 1921.

Application filed 4December 8, 1917. Serial No. 206,336.

To all whom t may concern Be it known that I, ALBERT S. Rowan, a citizenof the United States, residing in the city of Sedalia, State ofMissouri, have invented new and useful Improvements in Center-Plates, ofwhich the following is a specification, reference being had to theaccompanying drawings.

The present invention relates to new and useful improvements in centerplates and has for its special object the provision of what l term aroller bearing center plate.

The primary object of the invention is the provision of a center plateso constructed that all possible friction is eliminated.

Another object of the invention is the provision of a device of theabove specified character including a base having' bearing rollersmounted therein and a top plate adapted to Ht over the base to engagesaid bearing rollers whereby said top plate will be supported againstfriction.

Still another object of the present invention is the provision of adevice of the above character which will be comparatively simple andinexpensive to manufacture, reliable and eiiicient in use, and readilyoperated. p

lV ith the above and other objects in view the present invention residesin the novel features of construction, formations, combinations andarrangements of parts to be hereinafter more particularly described,claimed, and illustrated in the accompanying drawing forming a part ofthe present invention and in which;

Figure 1 is a perspective view of the device with the top plate removed;and

Fig. 2 is a transverse sectional view thereof.

Referring now to the accompanying drawing by corresponding characters ofreference throughout the several views, the numeral 5 designates ingeneral my improved center plate which consists of a base 6 and a topplate 7.

The base 6 includes a plate 8 having reinforcements 9 provided atintervals thereon through which apertures 10 are formed and by means ofwhich the base can be attached to any suitable means of support.

The plate 8 is provided in spaced relation from the periphery thereofwith an annular iiange 11 while disposed in spaced relation within thisflange 1l is a concentric sleeve or iiange 12.

A plurality of bearing rollers 13 are journaled upon pins or rods 14;which connect the ianges 11 and 12 and extend radially from the centerof the device.

These bearing rollers 13 are of conical formation as clearly shown in`the drawing and engage the under beveled side 15 of the top plate 7.

This plate 7 is provided with a flange 17 which fits over the beforementioned flange 11 whie the central portion thereof is formed with acircular projection 18 which fits within the iange or sleeve 12.

When the parts are assembled as shown in F ig. 2 of the drawing', itwill be noted that the bearing rollers 13 will support the top plate 7in such manner as to eliminate all possible friction.

From the foregoing description taken in connection with the accompanyingdrawing it will be manifest that a center plate is provided which can beapplicable for various purposes and which will fulfil all of thenecessary requirements of such a device.

Having thus fully described the invention what I claim is new and desireto protect by Letters Patent is;

1. A center bearing comprising a base provided with inner and outerupwardly extending flanges arranged in concentric relation, the outerflange extending higher than the inner ange, the inner flange having aplurality of sockets therein, the outer flange having a plurality ofopenings therein and alining with the respective sockets radially fromthe center of the device, pins fitted in said sockets through saidopenings, conical roller bearings journaled on said pins., a top platevhaving a beveled portion on its under side engaging the conical rollerbearings for supporting the plate against friction and also having acentral circular depending projection for engagement with the upper endof the inner flange and also provided with an annular depending flangeadapted to embrace the aforesaid outer flange and to lit over the outerends of the aforesaid pins.

2. A center bearing comprising a base having inner and outer annularflanges, the inner flange having a plurality of sockets therein, theouter iiange having a plurality ofopenings therein arranged inhorizontal spaced relation the sockets and alningV with the latterradially from the center of the base, pins fitting in the radiallyalining sockets and the "openings, roller bearings journaled on saidpins between said flanges, and a top plate mounted on said conicalroller bearings and having an annular de pending ange surrounding theouter surface of the aforesaid outer` flange of the base, and lying overthe outer ends of said 10 pins to prevent displacement of the latteroutwardly with relation to the first mentoned flanges.
